Storage Api: Add metrics (#85316)
* Storage server runs own instrumentation server if its the sole target. Starts adding some sample metrics for now.

* adds metric for failed optimistic locks

* refactors metrics registration to own method on service for testability. Adds tests.

* Register sql storage server metrics from within the service

* fixes test

* troubleshooting drone test failures. Maybe timing when starting instrumentation server?

* Waits until instrumentation server has started. Updates tests.

* defer wont get called unless theres an error. removing.

* wait for instrumentation server to be running

* linter - close res body

* use port 3000 for metrics and removes test metric inc() call

* fixes test - updates port

* refactors module server to provide an instrumentation server module when there is no ALL or CORE target provided and running as single target

* make instrumentation server a dependency of all modules that do not run their own http server

* adds module server test

* adds tests for instrumentation service and removes old tests that aren't needed

* ignore error in test

* uses helper to start and run service

* when running wait on ctx done or http server err

* wait for http server

* removes println

* updates module server test to be integration test

* require no error in goroutine

* skips integration test when GRAFANA_TEST_DB not defined

* move http server start into start, verify returned content

* make test error when run fails

* try waiting longer and see if drone tests pass

* update integration test mysql creds to match drone

* go back to only waiting half second

* debug log drone mysql connection string

* use same db connection config as drone

* try using same hostname as drone

* cant use localhost as mysql hostname in drone tests. Need to parse it from the cfg db connection string
